Your schematic contain unknown model lm317at

Took me 4-5 hours to design the circuit and with this i have to submit for Summer scholarship program.and in the end i get to see this error . I am fed up now please help me with this .Tried one solution but it did not work .

All the kicad components are not recognized in eSim. You need to add it on your own.
You can build its internal diagram using subcircuit builder or add its characteristics from the datasheet using device modeling.
For subcircuit builder:https://esim.fossee.in/resource/book/esimusermanual.pdf and for
device modeling:http://spoken-tutorial.org/tutorial-search/?search_foss=eSim&search_language=English

But that model lm317k and other lm317s are there in the library the circuits are already made the only point when I click to convert kicad to  ngspice it gives me errors. After hours of building these circuits when I click convert this error came in each of my 5 circuits. Then just for sake of experimenting I took a simple circuit then it got converted as that circuit had no ic in it but for plotting it gave error that is fatal error for plotting python graph

All kicad components in eeschema are compatible for PCB. But, if you need simulation results, the devices should be compatible with ngspice. If the device is not compatible with ngspice, then you will get the error as an unknown model.

So what to do if it shows unknown model while conversion in Windows 10 Pro????

You can build its internal diagram using subcircuit builder or add its characteristics from the datasheet using device modeling. You can find the links in the above answer.
